This invention is designed to improve radiators and is particularly designed with relation to electrically heated radiators. The purpose of the invention is to form a simple and efiicient radiating surface in connectlon with such heaters. Features and details of the invention will appear from the specification and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawings as follows Fig. 1 shows a front elevation of a radiator, a part being broken away to better show construction. a

Fig. 3 a section on the line in Fig. 2.

Fig. 5 a perspective view of a spacing and mounting plate. v

1 marks the radiator case. In this is arranged an electric heating unit 2. The electric heating unit as shown comprises the tubular water containers 3-3 which are connected by a manifold 3a. These are designed to be heated by an electric heating unit 3?).

Radiating plates 4 are preferably formed of highly conductive material and have the inturned flanges 5 at their edges so that When the plates are placed together the flanges 5 space the plates in parallel relation and thus form passages between them. The flanges 5 are arranged at the sides and thus form vertical passages through the plates through which air may circulate and take up the heat from the radiating plates. Spacer plates 6 are arranged between the plates 4. These spacer plates have openings through which the tubes 3 extend, these openings having spring iips 7 formed by slots 7 at. These spring lips permit of being readily placed on the ordinary tube and take up any irregularities in size and assure a spring-pressed contact between the spacer plate and the container tube so that there is a desirable heat exchange relation maintained between them.

. The spacer plates are provided with the spacer hold the inner parts of the plates 4 in spaced relation.

The radiating plates have openings 8 I through which the tubes 3 extend and these openings are surrounded by lips 9, the lips being provided with slots 9a to renderthem flexible, or resilient, the material of which the plates are made. being ordinarily more or less resilient. These spring lips 9 spring so as to conform to the shape of the lips 7 as they are sprung on the tubes 3. Thus there is esthis pressure with the edge materialof the lip.

in engagement is suflicient to effect a very positive engagement between the tube and each spacer-and consequently locks the radiatorplate elements in position without the use of solder, or other securing meansalong the tube. It'Will be noted that the spacingv flanges 5 have a slight return bend. This as.- sures the contact of the edges of these spac ing flanges even though there may be some irregularity in the placing of the plates.

While I have shown the tubular container as adapted to carry water it willbe understood that in the broader aspects of thisinvention I do not wishitolbe limited to a container adapted to retain water as all that-is necessary is that the container. contain the elements,or means for supplying the heat.

What I claim as new isf:

In a radiatorfthecombination of a tubular container; radiating plates having.

openings. through whichythe container extends; and spacer plates having spring- I lipped openings through which the container extends spacing the radiating plates and being in spring-pressed engagement with the container for conveying heat to the radiating plates.

2. In a radiator, the combination of a tubular container; spacer plates having openings therethrough through which the container extends, said spacer lates havin spacer shoulders thereon; and radiating'p ates arran ed in spaced relation to one another and agamst the shoulders of the spacing plates and in heat transfer relation thereto.

3. In a radiator, the combination of a tubular container; spacer plates having openings therethrough through which the container extends, said spacer plates having spacer shoulders thereon; and radiating plates arranged in spaced relation to one another and against the shoulders of the acer plates and in heat transfer relation t ereto, said spacer plates having spring-lipped openings, the lips of which engage the container with spring-pressed contact and the radiating plates havinn openings conforming to the spring-lipped openings of the spacer plates.

4. In a radiator, the combination of a tubular container; spacer plates having openings therethrough through which the container extends, said spacer plates having spacer shoulders thereon; radiating plates arranged in spaced relation to one another and against the shoulders of the spacer plates and in heat transfer relation thereto; and edge flan es I on the radiating plates spacing the radiatmg plates at their outer edges.

5.. In a radiator, the combination of a tubular container; spacer plates mounted on the container, said spacer plates having spring lip openings through which the container extends, sa-ld spacer plates being in springpressed engagement with the container; and radiator plates having openin s, the walls of which engage and surroun said spring lips whereby the sprin lips form' a mounting for the radiator p ates and the engagement of the spring lips with the container and with the walls of the openings of the radiator plates engaging the spring lips transfers heat from the container to the radiator plates.

6. In a radiator, the combination'of a tubular container;'spacer plates mounted on the container, said spacer plates having spring lipped openin s through which the container extends, said spacer plates being in springpressed engagement with the container; and radiating plates having spring lipped openings, sa1dspring lips conforming to the spring lips of the openings of the spacer plates and mounted thereon.

In testimony whereof I have hereunto set my hand.
